Correct, the content is the same. However, if you read the MTP book I listed up thread that's authored by Jason Kemp and then Samardan Presses' CE System Reference book, I believe you'll find MTP/Kemp's book as a better organized, more lucid presentation of the rules and overall better quality. I also own Cepheus Deluxe as well as Hostile Rules (both quality publications) and I consider MTP's take on the rules/SRD to be as good or better.
Glad to hear Jason Kemp was involved with this DLC - will definitely be buying it.
